[0003] In the process of lifting the upper vehicle body, the current lifting appliance usually has a part of structure extending between the upper vehicle body and the chassis. Therefore, the chassis needs to be designed to avoid the part of structure, which easily leads to the reduction of the strength of the corresponding part of the chassis. CONTENT OF THE UTILITY MODEL

[0004] In view of the above problems, the application provides a lifting appliance, an upper vehicle body and a vehicle, which can alleviate the problem that the extension of the lifting appliance between the upper vehicle body and the chassis leads to the reduction of the strength of the chassis.

[0006] a base, two supporting assemblies arranged at intervals along a first direction on the base, wherein each supporting assembly comprises at least two vertical arms arranged at intervals along a second direction, one end of each vertical arm is connected to the base, and the other end of each vertical arm is provided with a support piece for bearing the upper vehicle body, and the first direction and the second direction are arranged at an angle.

[0007] In the technical scheme of the embodiments, the lifting appliance comprises two supporting assemblies arranged at intervals to allow the upper vehicle body to be located between the two supporting assemblies, so that the two supporting assemblies can bear the upper vehicle body. The support pieces of different supporting assemblies are arranged at intervals to reduce the interference of the support pieces with the processing of the upper vehicle body. The interval arrangement of the support pieces of different supporting assemblies can also reduce the volume of the part of the support pieces located between the upper vehicle body and the chassis, thereby reducing the area of the avoidance design of the chassis and reducing the negative impact of the support pieces on the strength of the chassis. Each supporting assembly comprises at least two vertical arms to improve the stability and bearing capacity of the supporting assembly.

[0008] In some embodiments, the upper vehicle body comprises a skirt arranged at intervals along the first direction. In the first direction, the distance between the skirt and the adjacent vertical arm is greater than the distance between the skirt and the adjacent support piece.

[0066] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily independent or alternative embodiments to each other.

[0070] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the technical terms "mounting", "connection", "connection", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0071] In the vehicle assembly production conveying line, the assembly process of the chassis mainly relies on the aerial conveying tooling to complete, that is, mainly relies on the lifting appliance to complete. The lifting appliance can lift the upper body in the air, at this time the chassis can move to below the upper body and be spliced on the upper body.

[0072] In order to lift the upper body, at least part of the structure in the lifting appliance needs to be located below the upper body, and at present, the upper body is usually supported and lifted by a cross beam penetrating below the upper body. However, the chassis also needs to be assembled from below the upper body to the upper body, at this time the part of the structure in the lifting appliance supporting the upper body will interfere with the assembly of the chassis. At present, an avoidance structure (such as an avoidance slot) is usually arranged on the chassis to reduce the mutual interference between the lifting appliance and the chassis, but such arrangement is easy to cause the overall performance of the chassis to decrease, and is easy to cause the chassis to be insufficient in strength.

[0073] For the electric vehicle, there is currently a direct battery device as the floor of the electric vehicle, in which the space of the chassis determines the number of battery devices that can be installed on the vehicle and determines the cruising range of the vehicle. If the support structure of the spreader extending to the upper body is avoided, the number and volume of the battery devices that can be installed on the vehicle will be reduced, thereby easily causing the cruising range of the vehicle to be short.

[0074] Based on the above considerations, in order to alleviate the problem that the extension of the spreader between the upper body and the chassis reduces the strength of the chassis, and at the same time to enable the spreader to stably hoist the upper body, the embodiments of the present application provide a spreader, two support assemblies are arranged in a relative interval, and each support assembly includes at least two vertical arms, a support member is arranged at one end of the vertical arm to support the upper body through the support member.

[0075] In such a spreader, the two support assemblies can support the upper body on both sides of the upper body, and at least two support members are arranged in each spreader, that is, at least four support points are provided between the spreader and the upper body, so that the spreader can stably support the upper body; on this basis, the support members of different support assemblies are arranged in an interval to leave more assembly space for the upper body, thereby reducing the interference of the support members on the assembly of the upper body. For the upper body, this arrangement can reduce the length of the support member between the upper body and the chassis, thereby reducing the interference with the assembly of the chassis and reducing the avoidance arrangement of the chassis for the support member, thereby alleviating the negative impact of the support member on the strength of the chassis.

[0076] The embodiments of the present application disclose that the spreader can be used to hoist various upper bodies, and the following embodiments are described by taking a spreader of an embodiment of the present application as an example for hoisting an upper body and for installing a chassis.

[0077] Reference Figures 1 to 4 In a first aspect, some embodiments of the present application provide a spreader 100 for hoisting an upper body 200, the spreader 100 comprising a base 10 and two support assemblies 20. The two support assemblies 20 are arranged on the base 10 in a first direction at an interval; the support assembly 20 comprises at least two vertical arms 21 arranged at an interval in a second direction, one end of the vertical arm 21 is connected to the base 10, and the other end of the vertical arm 21 is provided with a support member 22, the support member 22 is used to support the upper body 200; the first direction and the second direction are arranged at an angle.

[0078] Figure 2 In the above embodiment, the direction in which the X-axis is located is the length direction of the spreader 100 and the length direction of the upper body 200; the direction in which the Y-axis is located is the width direction of the spreader 100 and the width direction of the upper body 200; the direction in which the Z-axis is located is the height direction of the spreader 100 and the height direction of the upper body 200.

[0079] The base 10 refers to a structure in the lifting appliance 100 for providing a fixed base for the supporting assembly 20 or other structures, which can be a frame structure, a block structure or other shaped structure; the shape of the base 10 can be cuboid, cylindrical or other shape; the material of the base 10 can include metal, plastic or other materials.

[0080] The supporting assembly 20 refers to a structure in the lifting appliance 100 for supporting the upper vehicle body 200, which is arranged on the base 10 and can be fixedly connected to the base 10 by welding, screwing or other means, or rotatably connected to the base 10 by hinging or other means.

[0081] The supporting assembly 20 has two, which are arranged along the first direction to form a lifting space between the two supporting assemblies 20, which is used to accommodate the upper vehicle body 200 to be lifted; the two supporting assemblies 20 can support the upper vehicle body 200 from opposite sides of the upper vehicle body 200, so that the lifting appliance 100 can stably lift the upper vehicle body 200.

[0082] The first direction can be the width direction Y of the lifting appliance 100, or the length direction X of the lifting appliance 100 or other direction; for example, the first direction is the width direction Y of the lifting appliance 100.

[0083] The supporting assembly 20 includes at least two vertical arms 21 and a support 22 arranged on the vertical arm 21.

[0084] The vertical arm 21 refers to a structure in the supporting assembly 20 for connecting the support 22, which can be a cylindrical structure, a prismatic structure or other shaped structure; one end of the vertical arm 21 is connected to the base 10, which can be fixedly connected to the base 10 by welding, screwing or other means, or rotatably connected to the base 10 by hinging or other means; the other end of the vertical arm 21 is connected to the support 22, which can be connected to the vertical arm 21 by welding, screwing or other means; the material of the vertical arm 21 can include metal, plastic or other materials.

[0085] The support 22 refers to a structure in the supporting assembly 20 for supporting and lifting the upper vehicle body 200, which can support the upper vehicle body 200 from the bottom of the upper vehicle body 200 to lift the upper vehicle body 200; the support 22 can include a plate structure, a column structure or other shaped structure; the material of the support 22 can include metal, plastic or other materials.

[0086] The support 22 can correspond to the inherent structure on the upper vehicle body 200 and support the corresponding part; additional structures can also be provided on the upper vehicle body 200 to make the structure correspond to the support 22 for the support 22 to support.

[0087] The number of the vertical arms 21 in one supporting assembly 20 is at least two, that is, the number of the vertical arms 21 in one supporting assembly 20 can be two, three or more. Since the support 22 is connected to one end of the vertical arm 21, one supporting assembly 20 also includes at least two supports 22; at this time, one supporting assembly 20 has at least two different supporting positions with the upper vehicle body 200, and two supporting assemblies 20 have at least four different supporting positions with the upper vehicle body 200, so that the lifting appliance 100 can more stably hoist the upper vehicle body 200.

[0088] Since the two supporting assemblies 20 are arranged in the first direction, the supports 22 in different supporting assemblies 20 are also arranged in the first direction; since the upper vehicle body 200 is located between the two supporting assemblies 20 in the first direction, the arrangement of the supports 22 in the first direction can reduce the length of the supports 22 located below the upper vehicle body 200, thereby reducing the interference of the supports 22 with the installation of the upper vehicle body 200 and the chassis.

[0089] In the process of assembling the upper vehicle body 200 and the chassis, the lifting appliance 100 first bears the upper vehicle body 200 and lifts the upper vehicle body 200. In this process, the support 22 enters below the upper vehicle body 200 and contacts and supports the upper vehicle body 200; then the base 10 is lifted, and the support 22 is lifted synchronously by the vertical arm 21, and the support 22 lifts the upper vehicle body 200; then the chassis is placed below the upper vehicle body 200 and assembled.

[0090] According to the above action process, in the process of assembling the chassis to the upper vehicle body 200, at least part of the support 22 located below the upper vehicle body 200 will be located between the chassis and the upper vehicle body 200, at this time, part of the support 22 will affect the assembly of the chassis to the upper vehicle body 200; in order to reduce the influence, the chassis is usually provided with a position avoiding structure (such as a position avoiding groove) to avoid the part of the support 22 located between the upper vehicle body 200 and the chassis, which results in that the structure of the chassis will be damaged and the strength is easily reduced.

[0091] Therefore, the embodiment arranges the supports 22 of different supporting assemblies 20 to be spaced apart, so as to reduce the interference of the supports 22 with the processing of the upper vehicle body 200; the arrangement of the supports 22 of different supporting assemblies 20 to be spaced apart can also reduce the volume of the part of the support 22 located between the upper vehicle body 200 and the chassis, thereby reducing the area of the position avoiding structure required by the chassis, and reducing the negative influence of the support 22 on the strength of the chassis.

[0092] Meanwhile, this embodiment also includes two support components 20 arranged at relative intervals in the lifting device 100, so that the upper vehicle body 200 can be located between the two support components 20, which facilitates the two support components 20 to support the upper vehicle body 200; and each support component 20 includes at least two vertical arms 21 to improve the stability and load-bearing capacity of the support component 20.

[0093] refer to Figure 1 , Figure 8 In some embodiments, the upper body 200 includes skirts 53 spaced apart along a first direction; in the first direction, the distance between the skirts 53 and the adjacent upright arm 21 is greater than the distance between the skirts 53 and the adjacent support member 22.

[0094] Skirt 53 refers to the edge of the bottom of the upper body 200. The inner side of skirt 53 is most of the upper body 200 and is also the chassis mounting area. The outer side of skirt 53 is the outer side of the upper body 200. For example, when the upper body 200 is the upper body structure of an electric vehicle, the chassis may include a battery device. In this case, the area inside skirt 53 also includes the battery device mounting area.

[0095] In the first direction, the boom 21 is located outside the upper body 200, and there is a gap between the boom 21 and the skirt 53 to reduce the occurrence of the boom 21 colliding with the upper body 200. At the same time, the gap also facilitates the operation of the upper body 200 by the staff.

[0096] The distance between the side skirt 53 and the vertical arm 21 in the first direction refers to the distance between the side skirt 53 and the closest part of the vertical arm 21 to the upper body 200 in the first direction. The distance between the side skirt 53 and the support member 22 in the first direction refers to the distance between the closest part of the support member 22 to the upper body 200 and the side skirt 53 in the first direction. The distance between the side skirt 53 and the vertical arm 21 in the first direction is greater than the distance between the side skirt 53 and the support member 22 in the first direction, that is, the support member 22 is located on the outside of the side skirt 53. Since the chassis is installed on the inside of the side skirt 53, this arrangement makes it difficult for any part of the support member 22 to extend to the inside of the side skirt 53, so that the support member 22 is difficult to enter between the chassis and the upper body 200, thereby reducing the interference of the support member 22 on the chassis installation.

[0097] Therefore, there is no need to install a clearance structure on the chassis to avoid the support member 22, which can improve the integrity of the chassis and reduce the negative impact of the support member 22 on the chassis strength.

[0098] In the example, when the upper body 200 is an upper body structure of an electric vehicle, the chassis can include a battery device and make the battery device as a floor of the vehicle, at this time the battery device is installed at the bottom of the upper body 200 and located at the inner side of the skirt 53; the distance between the skirt 53 and the support 22 is less than the distance between the skirt 53 and the vertical arm 21, so that the support 22 is located at the outer side of the skirt 53 and is difficult to intrude into the installation space of the chassis, at this time the battery device does not need to be designed to avoid the support 22, thereby improving the integrity of the battery device and reducing the strength loss caused by the battery device avoiding the support 22.

[0099] In the example, the distance between the skirt 53 and the support 22 is less than the distance between the skirt 53 and the vertical arm 21, so that the support 22 is difficult to extend between the upper body 200 and the chassis, and the chassis does not need to be designed to avoid the support 22, thereby reducing the interference of the support 22 to the installation of the upper body 200 and the chassis, and further reducing the negative impact of the support 22 on the strength of the chassis.

[0100] In some examples, the size of the support 22 in the first direction is less than or equal to 20 cm (centimeters).

[0101] Since the distance between the vertical arm 21 and the skirt 53 in the first direction is usually 20 cm, the size of the support 22 in the first direction should be less than or equal to 20 cm, so that the support 22 is difficult to extend to the inner side of the skirt 53, thereby reducing the interference of the support 22 to the installation of the chassis.

[0102] The size of the support 22 in the first direction refers to the distance between the two farthest ends of the support 22 in the first direction; the size can be 20 cm, or 19 cm, 18 cm, 17 cm, 16 cm, 15 cm or other values.

[0103] The longer the size of the support 22 in the first direction, the more likely the support 22 extends to the inner side of the skirt 53 of the upper body 200, and the greater the interference to the installation of the chassis; the shorter the size of the support 22 in the first direction, the closer the distance between the upper body 200 and the vertical arm 21, and the more likely to cause the collision between the vertical arm 21 and the upper body 200; if an additional structure is provided on the upper body 200 for the support 22 to bear, the shorter the size of the support 22 in the first direction, the longer the size of the additional structure in the first direction, and thus it is difficult to meet the processing requirements of the upper body 200.

[0104] For example, the support 22 can have a size of 20 cm in the first direction, and the closest part of the support 22 to the upper vehicle body 200 is located near the skirt 53. In this way, the support 22 can support the upper vehicle body 200, and it is difficult for the support 22 to extend to the inside of the skirt 53, and the distance between the vertical arm 21 and the upper vehicle body 200 is not too close, thereby reducing the risk of the vertical arm 21 colliding with the upper vehicle body 200.

[0105] For example, the support 22 can have a size of 18 cm in the first direction, and the closest part of the support 22 to the upper vehicle body 200 is located outside the skirt 53. In this way, the support 22 can support the upper vehicle body 200, and it is difficult for the support 22 to extend to the inside of the skirt 53, thereby reducing the interference of the support 22 on the chassis installation.

[0106] For example, the support 22 can have a size of 15 cm in the first direction, and the closest part of the support 22 to the upper vehicle body 200 is located outside the skirt 53. In this way, the support 22 can support the upper vehicle body 200, and it is far away from the skirt 53, thereby better reducing the interference of the support 22 on the chassis installation.

[0107] The embodiment provides a size range of the support 22, so that the support 22 is difficult to extend between the upper vehicle body 200 and the chassis, thereby reducing the negative impact of the support 22 on the strength of the chassis.

[0108] Reference Figure 2 、 Figures 5 to 7 In some embodiments, the support 22 includes a load-bearing part 221 connected to the corresponding vertical arm 21, and the load-bearing part 221 is used to support the upper vehicle body 200.

[0109] The load-bearing part 221 refers to a structure of the support 22 that is used to contact and support the upper vehicle body 200. The load-bearing part 221 can be a plate-shaped structure, a block-shaped structure, or a structure of other shapes. The shape of the load-bearing part 221 can be a rectangle, a circle, or other shapes. The material of the load-bearing part 221 can include metal, plastic, or other materials.

[0110] The load-bearing part 221 is connected to the vertical arm 21, that is, the load-bearing part 221 is connected to the side of the vertical arm 21 away from the base 10. The load-bearing part 221 can be directly connected to the vertical arm 21, or indirectly connected to the vertical arm 21 through an intermediate structure. In the case where the load-bearing part 221 is directly connected to the vertical arm 21, the load-bearing part 221 can be connected to the vertical arm 21 by welding, screwing, or the like.

[0111] In the case where the support 22 supports the upper vehicle body 200, the load-bearing part 221 can enter below the upper vehicle body 200 and support and hold the upper vehicle body 200, so as to lift the upper vehicle body 200 synchronously with the lifting of the base 10.

[0112] In the case that the distance between the support 22 and the skirt 53 is smaller than the distance between the vertical arm 21 and the skirt 53, the distance between the part of the load-bearing part 221 closest to the skirt 53 and the skirt 53 should also be smaller than the distance between the vertical arm 21 and the skirt 53.

[0113] In the case that the size of the support 22 in the first direction is smaller than or equal to 20 cm, the size of the load-bearing part 221 in the first direction should also be smaller than or equal to 20 cm.

[0114] The present embodiment provides some specific structures of the support 22, so that the support 22 includes the load-bearing part 221 to support the upper vehicle body 200 through the load-bearing part 221.

[0115] Reference Figure 2 、 Figures 5 to 7 In some embodiments, the load-bearing part 221 is provided with a positioning pin 222, which is located on the side of the load-bearing part 221 facing the base 10.

[0116] The positioning pin 222 refers to a structure in the support 22 for fixing the position of the upper vehicle body 200 relative to the support 22. The positioning pin 222 can be a prismatic structure, a cylindrical structure or other shaped structure. The positioning pin 222 is provided on the load-bearing part 221. The positioning pin 222 can be connected to the load-bearing part 221 by welding, screwing or other means. The positioning pin 222 can also be integrally formed with the load-bearing part 221. The material of the positioning pin 222 can include metal, plastic or other materials. The material of the positioning pin 222 can be the same as or different from that of the load-bearing part 221.

[0117] The upper vehicle body 200 is provided with a hole position opposite to the positioning pin 222 for the positioning pin 222 to insert. The hole position can be a hole structure inherent to the upper vehicle body 200 (such as a process hole, a mounting hole, etc.), or a hole structure specially provided for the positioning pin 222 to insert.

[0118] In the process of supporting the upper vehicle body 200 by the support 22, the load-bearing part 221 moves downward below the upper vehicle body 200. Then, the load-bearing part 221 rises, and the positioning pin 222 enters the corresponding hole position first. At this time, the positioning pin 222 can limit the movement of the upper vehicle body 200 in the radial direction of the positioning pin 222, thereby fixing the relative position of the upper vehicle body 200 and the load-bearing part 221. Then, the load-bearing part 221 continues to rise to contact and support the upper vehicle body 200, thereby lifting the upper vehicle body 200 to rise synchronously.

[0119] This embodiment provides specific structures for some support members 22, such that the support members 22 include positioning pins 222, so as to fix the position of the upper body 200 relative to the load-bearing part 221 by positioning pins 222, thereby enabling the upper body 200 to be fixed relative to the load-bearing part 221, so as to reduce the slippage and misalignment of the upper body 200.

[0120] In some embodiments, the load-bearing part 221 is a telescopic structural member, and the load-bearing part 221 can extend and retract along a first direction.

[0121] The load-bearing part 221 is a retractable structural component that can extend and retract along the first direction. The load-bearing part 221 can be a retractable rod, plate or other shaped structural component. The load-bearing part 221 can be an electrically retractable structure, a pneumatic retractable structure, a hydraulic retractable structure or other power-driven structure. The load-bearing part 221 can also be manually extended and retracted.

[0122] The load-bearing part 221 is telescopic along the first direction, that is, the size of the load-bearing part 221 in the first direction is adjustable, so that the load-bearing part 221 can adapt to various sizes of upper body 200, and facilitate the staff to adjust the length of the load-bearing part 221 as needed, so that the load-bearing part 221 can not only support the upper body 200, but also reduce the interference of the load-bearing part 221 on the chassis installation.

[0123] The specific structure of the load-bearing part 221 can be varied. For example, the load-bearing part 221 includes a fixed part and a movable part. The movable part can be movably sleeved outside the fixed part along a first square. The fixed part is connected to the upright arm 21, and the end of the movable part away from the fixed part is connected to a positioning pin 222. For example, the load-bearing part 221 includes a fixed part and a movable part. The fixed part is provided with a guide rail, and the movable part is slidably connected to the guide rail to move along a first direction. The fixed part is connected to the upright arm 21, and the end of the movable part away from the fixed part is connected to a positioning pin 222. The load-bearing part 221 can also include other telescopic structures, and is not limited to the two mentioned above.

[0124] In this embodiment, the load-bearing part 221 is a telescopic structural component so that the load-bearing part 221 can support the upper body 200 of various specifications and models.

[0125] refer to Figure 2 , Figures 5 to 7 In some embodiments, the side of the positioning pin 222 away from the upright arm 21 is flush with the side of the load-bearing part 221 away from the upright arm 21.

[0126] The side of the positioning pin 222 away from the upright arm 21 is flush with the side of the load-bearing part 221 away from the upright arm 21, that is, the positioning pin 222 is located at the farthest point of the load-bearing part 221 from the upright arm 21.

[0127] The position of the positioning pin 222 needs to be opposite to the upper vehicle body 200 because the positioning pin 222 is used to be inserted into the upper vehicle body 200 to fix the position of the upper vehicle body 200 relative to the load-bearing part. In addition, the support member 22 is located outside the skirt 53, so the positioning pin 222 should be opposite to the structure of the upper vehicle body 200 outside the skirt 53. In this way, the side of the positioning pin 222 away from the stand arm 21 is flush with the side of the load-bearing part 221 away from the stand arm 21, so that other positions of the load-bearing part 221 cannot easily extend to the inside of the skirt 53 and between the chassis and the upper vehicle body 200, thereby reducing the interference of the support member 22 on the installation of the chassis.

[0128] In the embodiment, the positioning pin 222 is located at the end of the load-bearing part 221 away from the stand arm 21, so as to reduce the length of the load-bearing part 221 extending between the upper vehicle body 200 and the chassis, thereby reducing the interference of the support member 22 on the installation of the chassis.

[0129] Reference Figure 7 In some embodiments, the positioning pin 222 includes a base 2221 connected to the load-bearing part 221, and a first guide part 2222 connected to the end of the base 2221 away from the load-bearing part 221, wherein the maximum width of the first guide part 2222 is smaller than the maximum width of the base 2221.

[0130] The base 2221 is the part of the positioning pin 222 connected to the load-bearing part 221, and is used to limit the relative position of the upper vehicle body 200 on the load-bearing part 221. In the case that the positioning pin 222 is inserted into the hole position of the upper vehicle body 200, the base 2221 can abut against the side wall of the hole position or the end surface of the hole position.

[0131] The base 2221 can be a cylindrical structure, a prismatic structure or other shaped structure. The base 2221 can be connected to the load-bearing part 221 by welding, screwing or other methods, or can be integrally formed with the load-bearing part 221. The material of the base 2221 can include metal, plastic or other materials.

[0132] The first guide part 2222 is a structure of the positioning pin 222 used to guide the position of the upper vehicle body 200 relative to the positioning pin 222, and is arranged at the side of the base 2221 away from the load-bearing part 221. In the process of the support member 22 approaching the upper vehicle body 200, the first guide part 2222 can contact the upper vehicle body 200 before the base 2221. In the case that the first guide part 2222 and the upper vehicle body 200 are slightly misaligned, the first guide part 2222 can guide the slight movement of the upper vehicle body 200 as the support member 22 rises, so that the hole position of the upper vehicle body 200 can correspond to the corresponding positioning pin 222.

[0133] The first guiding portion 2222 can be a cylindrical structure, a prismatic structure or other columnar structure, and a slope can be arranged on the side of the first guiding portion 2222 facing the upper vehicle body 200 to guide the movement of the upper vehicle body 200. The first guiding portion 2222 can also be a conical structure such as a cone or a pyramid, or a table-shaped structure such as a circular table or a prismatic table, to guide the movement of the upper vehicle body 200 through the slope of the structure.

[0134] The first guiding portion 2222 is connected to the base portion 2221, and the first guiding portion 2222 can be connected to the base portion 2221 by welding, screwing or other methods. The first guiding portion 2222 can also be integrally formed with the base portion 2221. The material of the first guiding portion 2222 can include metal, plastic or other materials, and the material of the first guiding portion 2222 can be the same as or different from that of the base portion 2221.

[0135] The width of the first guiding portion 2222 refers to the maximum linear dimension of the orthographic projection of the first guiding portion 2222 on a plane parallel to the bearing portion, and the width of the base portion 2221 refers to the maximum linear dimension of the orthographic projection of the base portion 2221 on a plane parallel to the bearing portion. The maximum width of the first guiding portion 2222 is less than the maximum width of the base portion 2221, so that the first guiding portion 2222 can enter the hole position of the upper vehicle body 200 corresponding to the positioning pin 222.

[0136] When the maximum width of the first guiding portion 2222 is less than the maximum width of the base portion 2221, the maximum size of the base portion 2221 can be less than the minimum diameter of the hole position of the upper vehicle body 200, so that the base portion 2221 can enter the hole position and abut against the side wall of the hole position to limit the movement of the upper vehicle body 200. The maximum size of the base portion 2221 can also be greater than the minimum diameter of the hole position of the upper vehicle body 200, so that the base portion 2221 cannot enter the hole position and functions to support the upper vehicle body 200, and the bearing portion 221 indirectly supports the upper vehicle body 200 through the base portion 2221.

[0137] The embodiment provides specific structures of the positioning pin 222, so that the positioning pin 222 can not only fix the position of the upper vehicle body 200 relative to the bearing portion 221, but also function as a guiding positioning part to facilitate the assembly of the positioning pin 222 and the upper vehicle body 200.

[0138] Reference Figure 7 In some embodiments, the first guiding portion 2222 is connected to the second guiding portion 2223 at the end away from the base portion 2221, and the second guiding portion 2223 is tapered in the direction of the base portion 2221 pointing to the second guiding portion 2223.

[0139] The second guiding portion 2223 is a structure of the positioning pin 222 for guiding the relative position of the upper vehicle body 200 to the positioning pin 222, and is arranged on the side of the first guiding portion 2222 away from the load-bearing portion 221. During the process of the support 22 approaching the upper vehicle body 200, the second guiding portion 2223 can contact the upper vehicle body 200 before the first guiding portion 2222 and the base portion 2221, and in the case of small misalignment between the second guiding portion 2223 and the upper vehicle body 200, the second guiding portion 2223 can guide the slight movement of the upper vehicle body 200 as the support 22 rises, so that the hole position of the upper vehicle body 200 can correspond to the corresponding positioning pin 222.

[0140] The second guiding portion 2223 is tapered in the direction of the base portion 2221 pointing to the second guiding portion 2223, that is, the width of the end of the second guiding portion 2223 away from the first guiding portion 2222 is smaller than the width of the end of the second guiding portion 2223 close to the first guiding portion 2222. Accordingly, the second guiding portion 2223 at least includes a slope inclined inward in the direction of the base portion 2221 pointing to the second guiding portion 2223 to guide the movement of the upper vehicle body 200.

[0141] The second guiding portion 2223 can be a conical, pyramidal or other conical structure, and the second guiding portion 2223 can also be a circular platform, a prismatic platform or other platform structure to guide the movement of the upper vehicle body 200 through the slope of the structure.

[0142] The second guiding portion 2223 is connected to the base portion 2221, and can be connected to the base portion 2221 by welding, screwing or other means. The second guiding portion 2223 can also be integrally formed with the base portion 2221. The material of the second guiding portion 2223 can include metal, plastic or other materials, and the material of the second guiding portion 2223 can be the same as or different from that of the base portion 2221.

[0143] During the process of the support 22 approaching the upper vehicle body 200, the second guiding portion 2223 can contact the upper vehicle body 200 before the first guiding portion 2222 and the base portion 2221, and in the case of small misalignment between the second guiding portion 2223 and the upper vehicle body 200, the second guiding portion 2223 can guide the slight movement of the upper vehicle body 200 as the support 22 rises, so that the hole position of the upper vehicle body 200 can correspond to the corresponding positioning pin 222.

[0144] The present embodiment further provides some structures of the positioning pin 222 to better guide the positioning pin 222 to better facilitate the assembly of the positioning pin 222 and the upper vehicle body 200.

[0145] Reference Figure 7In some embodiments, the support 22 further comprises a connecting portion 223 connected to the load-bearing portion 221, the connecting portion 223 being connected to the vertical arm 21, and the vertical arm 21 being indirectly connected to the vertical arm 21 through the connecting portion 223; a reinforcing rib 224 is arranged at the connection between the connecting portion 223 and the load-bearing portion 221.

[0146] The connecting portion 223 refers to a structure in the support 22 for connecting the load-bearing portion 221 and the vertical arm 21, the connecting portion 223 can be a plate-shaped structure, or a columnar structure or other shaped structure; the shape of the connecting portion 223 can be square, or circular or other shape; the material of the connecting portion 223 can include metal, plastic or other materials, and the material of the connecting portion 223 can be the same as or different from that of the load-bearing portion 221.

[0147] One side of the connecting portion 223 is connected to the vertical arm 21, and the other side is connected to the load-bearing portion 221, so that the support 22 can be more stably connected to the vertical arm 21; the connecting portion 223 can be connected to the vertical arm 21 by welding, screwing or other means, the connecting portion 223 can be connected to the load-bearing portion 221 by welding, screwing or other means, or the connecting portion 223 can be integrally formed with the load-bearing portion 221.

[0148] For example, the connecting portion 223 is a plate-shaped structure, and the load-bearing portion 221 is also a plate-shaped structure, the connecting portion 223 is perpendicular to the load-bearing portion 221, and the connecting portion 223 is integrally formed with the load-bearing portion 221.

[0149] The reinforcing rib 224 refers to a structure in the support 22 for improving the connection strength between the load-bearing portion 221 and the connecting portion 223, the reinforcing rib 224 can be a plate-shaped structure, or a strip-shaped structure or other shaped structure; the shape of the reinforcing rib 224 can be square, or triangular or other shape; the material of the reinforcing rib 224 can include metal, plastic or other materials, and the material of the reinforcing rib 224 can be the same as or different from that of the load-bearing portion 221.

[0150] One end of the reinforcing rib 224 is connected to the connecting portion 223, and the other end is connected to the load-bearing portion 221, so that the load-bearing portion 221 can be more stably connected to the connecting portion 223; the reinforcing rib 224 can be connected to the connecting portion 223 by welding, screwing or other means, and the reinforcing rib 224 can be connected to the load-bearing portion 221 by welding, screwing or other means.

[0151] The present embodiment provides some structures of the support 22, a reinforcing rib 224 is arranged between the connecting portion 223 and the load-bearing portion 221 to improve the load-bearing performance of the load-bearing portion 221 and the overall strength of the support 22.

[0152] Reference Figures 1 to 4In some embodiments, the plurality of supports 22 in the same support assembly 20 are spaced apart along the second direction.

[0153] One support assembly 20 includes at least two vertical arms 21, and each vertical arm 21 is provided with a support 22, that is, one support assembly 20 includes at least two supports 22; the supports 22 in the same support assembly 20 are spaced apart along the second direction, that is, the supports 22 in the same support assembly 20 can lift different parts of the upper vehicle body 200 along the second direction, so as to more stably support the upper vehicle body 200.

[0154] The spacing of the plurality of supports 22 in the same support assembly 20 can also reduce the space occupied by the supports 22 for the installation of the upper vehicle body 200, so as to further reduce the interference of the supports 22 with the chassis installation; at the same time, it can also reduce the interference of the supports 22 with the work of the workers.

[0155] In other embodiments, a first connecting beam 23 is arranged between two adjacent supports 22 in the same support assembly 20, and the two ends of the first connecting beam 23 are respectively connected to the two adjacent supports 22. In the first direction, the size of the first connecting beam 23 is smaller than the size of the support 22.

[0156] The first connecting beam 23 refers to a structure between the two adjacent supports 22 in the support assembly 20, and the first connecting beam 23 is used to connect the two adjacent supports 22, that is, the two ends of the first connecting beam 23 are respectively connected to the two adjacent supports 22; the first connecting beam 23 can be a cylindrical, prismatic or other shaped beam structure; the first connecting beam 23 can be connected to the corresponding support 22 by welding, screwing or other means; the material of the first connecting beam 23 can include metal, plastic or other materials.

[0157] For example, the first connecting beam 23 can be connected to the load-bearing part 221 of the support 22, or can be connected to the connecting part 223.

[0158] For example, in the case where one support assembly 20 includes two supports 22, the support assembly 20 includes one first connecting beam 23 which is located between the two supports 22; for example, in the case where one support assembly 20 includes three or more supports 22, a first connecting beam 23 can be arranged between any two adjacent supports 22.

[0159] The arrangement of the first connecting beam 23 can improve the integrity of the support assembly 20, and can also make the stress of each support 22 uniform, while improving the supporting capacity of each support 22.

[0160] In the case that the distance between the first support 22 and the skirt 53 in the first direction is less than the distance between the vertical arm 21 and the skirt 53, the distance between the first connecting beam 23 and the skirt 53 should also be less than the distance between the vertical arm 21 and the skirt 53, which can make the first connecting beam 23 located outside the skirt 53, so as to reduce the risk that the first connecting beam 23 extends between the chassis and the upper vehicle body 200, thereby reducing the interference of the first connecting beam 23 to the installation of the chassis.

[0161] The embodiment provides the positional relationship between the supports 22 in the same supporting assembly 20, so that the supports 22 are arranged at intervals, so as to further reduce the interference of the supports 22 to the processing of the upper vehicle body 200; and the first connecting beam 23 is arranged between the two adjacent supports 22, so as to improve the bearing performance of each support 22.

[0162] Reference Figures 1 to 4 In some embodiments, the vertical arm 21 is rotationally connected to the base 10, so that the supports 22 of the two supporting assemblies 20 can be close to or away from each other.

[0163] The vertical arm 21 is rotationally connected to the base 10, and the vertical arm 21 can be rotationally connected to the base 10 through a hinge or the like; the vertical arm 21 is rotationally connected to the base 10, that is, the vertical arm 21 can rotate around its rotation axis, so as to drive the supports 22 to rotate around their rotation axes.

[0164] The rotation of the vertical arm 21 can drive the two supporting assemblies 20 to be close to or away from one end of the base 10, that is, the rotation of the vertical arm 21 can drive the supports 22 of different supporting assemblies 20 to be close to or away from each other; in the case that the vertical arm 21 rotates and drives the supports 22 of different supporting assemblies 20 to be close to each other, the supports 22 can move to the lower side of the upper vehicle body 200, at this time, the lifting of the base 10 can make the supports 22 contact and support the upper vehicle body 200, so as to drive the upper vehicle body 200 to be lifted; in the case that the vertical arm 21 rotates and drives the supports 22 of different supporting assemblies 20 to be away from each other, the supports 22 can be away from the upper vehicle body 200, so as to facilitate the taking out and replacement of the upper vehicle body 200.

[0165] In the embodiment, the vertical arm 21 is rotationally connected to the base 10, so that the vertical arm 21 can drive the supports 22 to move to the lower side of the upper vehicle body 200, thereby facilitating the supports 22 to support the upper vehicle body 200; and the vertical arm 21 can also drive the supports 22 to exit from the lower side of the upper vehicle body 200, thereby facilitating the supports 22 to be away from the upper vehicle body 200.

[0166] Reference Figures 1 to 4 In some embodiments, the second connecting beam 24 is arranged between the two adjacent vertical arms 21 of the supporting assembly 20, and the two ends of the second connecting beam 24 are respectively connected to the two adjacent vertical arms 21.

[0167] The second connecting beam 24 refers to a structure between two adjacent vertical arms 21 in the supporting assembly 20, and is used to connect the two adjacent vertical arms 21, i.e., the two ends of the second connecting beam 24 are connected to the two adjacent vertical arms 21 respectively. The second connecting beam 24 can be a cylindrical beam structure, a prismatic beam structure or other shaped beam structure. The second connecting beam 24 can be connected to the corresponding support member 22 by welding, screwing or other methods. The material of the second connecting beam 24 can include metal, plastic or other materials.

[0168] For example, in the case where one supporting assembly 20 includes two vertical arms 21, the supporting assembly 20 includes one second connecting beam 24 between the two vertical arms 21. For example, in the case where one supporting assembly 20 includes three or more vertical arms 21, a second connecting beam 24 can be arranged between any two adjacent vertical arms 21.

[0169] Since the supporting assembly 20 includes two or more vertical arms 21, the second connecting beam 24 is used to connect the vertical arms 21 in the same supporting assembly 20, so that the vertical arms 21 can move synchronously, thereby facilitating the supporting assembly 20 to support or disengage the upper vehicle body 200. At the same time, the second connecting beam 24 can also improve the force distribution of the vertical arms 21, thereby improving the load bearing capacity of the vertical arms 21.

[0170] In this embodiment, the second connecting beam 24 is used to connect the two adjacent vertical arms 21 in the same supporting assembly 20, so that the vertical arms 21 can move synchronously, thereby facilitating the supporting assembly 20 to support or disengage the upper vehicle body 200. At the same time, the second connecting beam 24 can also improve the load bearing capacity of the vertical arms 21.

For example, a preset track can be arranged in the air above a work site, so that the base 10 is driven by the moving assembly 30 to move in the air, thereby facilitating the lifting of the upper vehicle body 200 by the lifting assembly 100 through the supporting assembly 20.

[0174] The lifting assembly 40 refers to an assembly in the lifting assembly 100 for driving the base 10 to lift, so as to adjust the height of the upper vehicle body 200 after the supporting assembly 20 lifts the upper vehicle body 200. For example, after the supporting assembly 20 lifts the upper vehicle body 200, the lifting assembly 40 can be controlled to lift the upper vehicle body 200, so as to increase the height between the upper vehicle body 200 and the ground, thereby facilitating the movement of the moving assembly to the lower side of the upper vehicle body 200 and facilitating the combination of the chassis and the upper vehicle body 200 by the workers.

[0175] The lifting assembly 40 can include a hydraulic lifting structure, an electric hoist, etc. The lifting assembly 40 can be arranged on the base 10 by welding, screwing, or the like. According to needs, the lifting assembly 40 can directly act on the ground or can act on a preset platform, track, etc.

[0176] For example, the lifting assembly 100 can include a carrying platform, the carrying platform is movably connected to the base 10, and the carrying platform is slidingly connected to a preset track. The base 10 is driven by the moving assembly 30 to move, which can drive the carrying platform to move synchronously. One end of the lifting assembly 40 is connected to the base 10, and the other end is connected to the carrying platform. The lifting assembly 40 can drive the base 10 to approach or move away from the carrying platform, so as to drive the base 10 to lift or descend.

[0177] The lifting assembly 100 can only include the moving assembly 30 or the lifting assembly 40, or can simultaneously include the moving assembly 30 and the lifting assembly 40.

[0178] In the embodiment, the lifting assembly 100 includes the moving assembly 30 and / or the lifting assembly 40, so as to drive the base 10 to move by the moving assembly 30 or to lift by the lifting assembly 40.

[0179] In some embodiments, the lifting assembly 100 includes the base 10, the supporting assembly 20, the moving assembly 30, and the lifting assembly 40.

[0180] The supporting assembly 20 has two and is arranged at intervals along the width direction Y of the lifting assembly 100, so that the upper vehicle body 200 can be located between the two supporting assemblies 20.

[0181] The supporting assembly 20 comprises two vertical arms 21, one end of the vertical arm 21 is rotatably connected to the base 10, and the other end of the vertical arm 21 is connected with a support 22; the support 22 comprises a connecting portion 223 connected to the vertical arm 21, a bearing portion 221 provided on the side of the connecting portion 223 away from the vertical arm 21, a reinforcing rib 224 connected to the connecting portion 223 and provided on the bearing portion 221, and a positioning pin 222 connected to the side of the bearing portion 221 away from the connecting portion 223.

[0182] The positioning pin 222 comprises a base portion 2221 connected to the bearing portion 221, a first guide portion 2222 connected to the end of the base portion 2221 away from the bearing portion 221, and a second guide portion 2223 in the shape of a circular truncated cone connected to the end of the first guide portion 2222 away from the base portion 2221, wherein the diameter of the first guide portion 2222 is smaller than the diameter of the base portion 2221.

[0183] The supporting assembly 20 further comprises a second connecting beam 24 provided between and connected to the two vertical arms 21.

[0184] The moving assembly 30 and the lifting assembly 40 are connected to the base 10.

[0185] The rotation of the supporting assembly 20 relative to the base 10 can drive the support 22 to move to the lower side of the upper vehicle body 200 through the vertical arm 21; then, the lifting of the base 10 can drive the support 22 to lift through the vertical arm 21; during the lifting of the support 22, the positioning pin 222 is first inserted into the corresponding hole position of the upper vehicle body 200, and then the bearing portion 221 contacts and lifts the upper vehicle body 200 to be lifted synchronously.

[0186] In a second aspect, with reference to Figures 8 to 10 The embodiments of the present application also provide an upper vehicle body 200 for being supported by the lifting appliance 100 provided by some embodiments of the first aspect.

[0187] The upper vehicle body 200 comprises an upper vehicle body main body 50, two first support portions 511 and two second support portions 521. The two first support portions 511 are both provided on the upper vehicle body main body 50 and are provided on the two sides of the upper vehicle body 200 along a first direction, and the first support portion 511 corresponds to the support 22; the two second support portions 521 are both provided on the upper vehicle body main body 50 and are provided on the two sides of the upper vehicle body 200 along the first direction, and the second support portion 521 corresponds to the support 22.

[0188] The upper vehicle body main body 50 is a main part of the upper vehicle body 200, which can comprise A-pillar, B-pillar, C-pillar, roof beam and the like.

[0189] The first support part 511 and the second support part 521 each refer to a structure in the upper vehicle body 200 for being opposite to the support piece 22, wherein the first support part 511 is located at the front part of the upper vehicle body 200, i.e. the front part in the direction of travel of the vehicle, and the second support part 521 is located at the rear part of the upper vehicle body 200, i.e. the rear part in the direction of travel of the vehicle.

[0190] The first support part 511 is two, and the two first support parts 511 are respectively arranged on both sides of the upper vehicle body 200 along a first direction, i.e. the two first support parts 511 respectively correspond to the two support pieces 22 which are arranged opposite and spaced apart in the two supporting assemblies 20; for example, the first direction is the width direction of the vehicle.

[0191] Similarly, the second support part 521 is two, and the two second support parts 521 are respectively arranged on both sides of the upper vehicle body 200 along a second direction, i.e. the two second support parts 521 respectively correspond to the two support pieces 22 which are arranged opposite and spaced apart in the two supporting assemblies 20; for example, the second direction is the width direction of the vehicle.

[0192] The first support part 511 and the second support part 521 can be independent structures and are connected to the upper vehicle body main body 50 by welding, screwing or the like, or can be inherent structures in the upper vehicle body 200.

[0193] Holes can be provided on the first support part 511 and the second support part 521 for the positioning pin 222 to be inserted; for example, the first support part 511 is provided with a first through hole 512, and the second support part 521 is provided with a second through hole 522, and the first through hole 512 and the second through hole 522 are respectively used for the positioning pin 222 of the corresponding support piece 22 to be inserted.

[0194] Reference Figures 8 to 10 In some embodiments, the upper vehicle body 200 further comprises a front fender 51 and a rear quarter panel 52 arranged on the upper vehicle body main body 50, the first support part 511 is located below the front fender 51, and the second support part 521 is located below the rear quarter panel 52.

[0195] The front fender 51 refers to a part of the upper vehicle body 200, and the front fender 51 is configured as an outer panel on the side of the vehicle above the front wheel of the vehicle, which serves to provide a wheel arch and reduce wind resistance.

[0196] The rear quarter panel 52 refers to a part of the side of the upper vehicle body 200, and the rear quarter panel 52 is located in the rear area of the vehicle, covering the rear half of the upper vehicle body 200 on both sides, and the rear quarter panel 52 can extend from the rear door to the tail lamp mounting position; for example, the rear quarter panel 52 can include a C-pillar inner panel, a C-pillar reinforcement panel, a rear quarter panel 52 transverse reinforcement panel, and a wheel cover bracket, etc.

[0197] The lower side of the front fender 51 refers to the side of the front fender 51 facing the ground; the front fender 51 is usually located outside the skirt 53 of the upper vehicle body 200, and the first support part 511 needs to be located outside the skirt 53 of the upper vehicle body 200, so the first support part 511 is arranged below the front fender 51 to shield the first support part 511 by the front fender 51, thereby reducing the negative impact of the first support part 511 on the overall performance and shape of the upper vehicle body 200.

[0198] The lower side of the rear quarter panel 52 refers to the side of the rear quarter panel 52 facing the ground; the rear quarter panel 52 is usually located outside the skirt 53 of the upper vehicle body 200, and the second support part 521 needs to be located outside the skirt 53 of the upper vehicle body 200, so the second support part 521 is arranged below the rear quarter panel 52 to shield the second support part 521 by the rear quarter panel 52, thereby reducing the negative impact of the second support part 521 on the overall performance and shape of the upper vehicle body 200.

[0199] In the embodiment, the first support part 511 and the second support part 521 are respectively arranged below the front fender 51 and the rear quarter panel 52; since the front fender 51 and the rear quarter panel 52 are both located outside the skirt 53 of the upper vehicle body 200, and the first support part 511 and the second support part 521 are both used to be opposite to the support member 22, the arrangement can enable the support member 22 to support the upper vehicle body 200 without extending into the skirt 53 of the upper vehicle body 200, thereby reducing the interference of the support member 22 with the chassis installation.

[0200] Reference Figures 8 to 10 In some embodiments, the first support part 511 is a part of the front fender 51, and the second support part 521 is a part of the rear quarter panel 52.

[0201] The first support part 511 is a part of the front fender 51 to simplify the structure of the upper vehicle body 200; for example, a through hole can be formed on the side of the front fender 51 facing the ground, and at this time, the part of the front fender 51 facing the ground can be used as the first support part 511, and the through hole can be used as the first through hole 512.

[0202] Similarly to the first support part 511, the second support part 521 is a part of the rear quarter panel 52 to simplify the structure of the upper vehicle body 200; for example, a through hole can be formed on the side of the rear quarter panel 52 facing the ground, and at this time, the part of the rear quarter panel 52 facing the ground can be used as the second support part 521, and the through hole can be used as the second through hole 522.

[0203] In the embodiment, the first support part 511 and the second support part 521 are respectively part of the front fender 51 and the rear quarter panel 52, the first support part 511 and the second support part 521 are arranged by using the structure of the upper body 200, the structure of the upper body 200 is simplified, and the negative influence of the first support part 511 and the second support part 521 on the upper body 200 is reduced.

[0204] Reference Figures 8 to 10 In some embodiments, the chassis mounting position 54 is arranged on the upper body 50, the chassis mounting position 54 is located between the two first support parts 511, and the chassis mounting position 54 is located between the two second support parts 521; the chassis mounting position 54 is arranged apart from the first support part 511, and the chassis mounting position 54 is arranged apart from the second support part 521.

[0205] The chassis mounting position 54 refers to a position on the upper body 50 for mounting the chassis, and can be a position arranged on the upper body 50 or a structure surrounded by the upper body 50.

[0206] The chassis mounting position 54 is located between the two first support parts 511, and the chassis mounting position 54 is located between the two second support parts 521; because the two first support parts 511 are arranged apart along the first direction, and the two second support parts 521 are arranged apart along the second direction, the chassis mounting position 54 is located between the two opposite first support parts 511, and the chassis mounting position 54 is located between the two opposite second support parts 521.

[0207] For example, when the first support part 511 and the second support part 521 are located outside the skirt 53, the chassis mounting position 54 can be located inside the skirt 53.

[0208] Because the first support part 511 and the second support part 521 are used to be opposite to the support part 22, the chassis mounting position 54 is arranged apart from the first support part 511, and the chassis mounting position 54 is arranged apart from the second support part 521. During the process of hoisting the upper body 200 by the hoist 100, the support part 22 is difficult to enter the chassis mounting position 54, so as to reduce the interference of the support part 22 on the process of mounting the chassis; at the same time, the chassis does not need to be provided with a position avoiding structure for avoiding the support part 22, so as to improve the integrity of the chassis and reduce the negative influence of the support part 22 on the strength of the chassis.

[0209] For example, in the case that the upper body 200 is an upper body structure of an electric vehicle, the chassis can include a battery device and make the battery device as a floor of the vehicle, at this time, the battery device is located in the chassis mounting position 54 and is installed on the upper body 200; since the chassis mounting position 54 is spaced apart from the first support part 511 and the second support part 521, the support part 22 is difficult to intrude into the chassis mounting position 54 during hoisting of the upper body 200 and installation of the battery device, at this time, the battery device does not need to be provided with a position avoiding structure for the support part 22, thereby improving the integrity of the battery device and reducing the strength loss caused by the battery device avoiding the support part 22.

[0210] In the embodiment, the chassis mounting position 54 is arranged on the upper body 200, and the first support part 511 and the second support part 521 are both spaced apart from the chassis mounting position 54, so as to reduce the interference and damage of the first support part 511 and the second support part 521 to the chassis, thereby improving the overall performance of the chassis.

[0211] In the third aspect, some embodiments of the present application further provide a vehicle including the vehicle body provided by some embodiments of the second aspect. In the vehicle, due to the arrangement of the first support part 511 and the second support part 521, the chassis does not need to avoid the support part 22 during the splicing of the upper body 200 and the chassis, and the integrity and strength of the chassis are improved.

[0212] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
